Peristaltic / Roller Pump
thingiverse
We designed this pump as a science project as we wanted something quite large that moved alot of water. Most of the other ones we found were very small and moved small amounts of fluid. This one would pump at least a liter per minute, probably alot more. A reasonably powerful motor is required to drive it, we found the best was a cordless drill on a slow speed setting, Do not drive it too fast. The following items are required to complete it: 2x Skateboard Bearings for the main arm (8mm ID, 22mm OD, 7mm Wide) 4x bearings for the rollers (19x6x6mm) 2x 35mm m6 bolts and lock nuts for the rollers 1x 80mm m8 bolt and locknot for the main axel 1m silicon tube 10mm ID, 15mm OD
